Accomplishments/Collaborations: HydroGEN Collaborative R&D Technical Highlights
Photoelectrochemical (PEC) Water SplittingUM achieved a first demonstration of a functional Si/InGaNtandem photoelectrode. A GaN/Si photocathode with stable operation (>100 h) at ~38 mA/cm2, without using surface protection, was also demonstrated. UM is focused on developing Si-based, low cost, high efficiency (>15%), and stable (>1,000 h) PEC tandem water splitting devices, using scalable, low cost semi-conductors, nanowire tunnel junction, and N-rich GaN self-protection. The photoelectrodes were characterized and optimized by the NREL and LBNL nodes, while LLNL carried out modeling to understand the protection role of N-rich GaN surfaces.
Low Temperature Electrolysis (LTE)NEU and UD demonstrated high AEM electrolyzer performance (0.46 A/cm2 at 1.8 V, 85°C), using PGM-free Ni-Fe/Raney Ni OER and NiCr/C HER catalysts, PAP-TP-MQN AEM, and 1% K2CO3 solution, enabling durable, high-performing materials for efficient and low cost H2 production. LBNL and SNL modeling nodes helped NEU better understand the AEM/catalyst interface, NREL nodes helped NEU characterize the membrane physical properties and optimize the catalyst formulation.

Accomplishments/Collaborations: HydroGEN Collaborative R&D Technical Highlights
High Temperature Electrolysis (HTE)United Technologies Research Center (UTRC), with help from INL, LBNL , and NREL nodes, identified high performance proton-electrolytes and steam electrodes that resulted in button cell performance exceeding the DOE performance target, stable protective coatings for 500 h, and a cell model for SOEC performance characterization and cell/stack operation simulation. The HydroGEN nodes provided critical support by addressing technical barriers in metal alloy durability, electrode/electrolyte material optimization and stability, and SOEC modeling.
Solar Thermochemical (STCH) Water SplittingCSM exceeded its hydrogen production target of 59 µmol H2/g sample by producing 218 and 247 µmol H2/g using two compositions within CexSr2-xMnO4 family, x = 0.1 and 0.2, respectively. This promising performance further motivates the search for additional perovskite compounds with STCH water splitting properties. The objective is to discover new STCH materials that can meet steam to hydrogen efficiency of 20% and low cost H2 production. The project leverages NREL and SNL modeling, material synthesis and characterization nodes.

HydroGEN: Advanced Water Splitting Materials 25
Responses to Previous Year Reviewers’ Comments
• The fact that about half of the 80+ nodes (capabilities) are being utilized suggests that the interaction with the HydroGEN-supported R&D projects/community is a benefit toward helping DOE realize its goals. It is unclear how to put into perspective the number of users, page views, downloads, etc., as well as the publications and presentations, and whether these are helping DOE achieve its goals/targets. As HydroGEN “matures,” a better metric would be clear evidence of how the nodes had an impact in making measurable/quantifiable benefits toward advancing R&D to meet DOE goals.
Response: We agree that testimonials and specific points of collaboration as witnessed by joint publications and presentations will be key in evaluating whether the nodes are providing critical or ancillary support for the FOA projects. Furthermore, cost reduction and technology maturity remain key metrics for success of the EMN.
• Probably one of the most pressing issues under Proposed Future Work is the development of an effective data management program, not so much in managing the data but in presenting to the R&D community in a format that is of value to the community. Developing benchmarking standard protocols and metrics is another pressing issue to make sure that the protocols for evaluating the various technologies provide an apples-to-apples comparison.
Response: We agree and are currently working on the data management in terms of dissemination with full metadata. In terms of protocols and metrics, this is an active area of work with the Benchmarking team lead by NEL/Proton OnSite, where HydroGEN core labs are actively engaged in helping to evaluate and establish the protocols.
HydroGEN: Advanced Water Splitting Materials 26
Responses to Previous Year Reviewers’ Comments
• Some of the secondary, visible metrics, such as the use of the data hub (~250 data files in a year), should get more emphasis either on boosting participation or in communicating the complexity of the data contained within the hub. There is ambiguity as to what a single file contains: whether it is a single resistance measurement or a summary from an entire collection of measurements from a unique tool on the beamline. In short, if the scale of the databank were conveyed in person-hours per data file that makes up the ~250 total, that could strike an audience as more impressive/appropriate than leaving the number of files to remain as an abstract concept, which risks sounding underwhelming.
Response: There has been lots of activities in the data hub this past year, hence there are 2 slides on data, summarizing the publication process developed, the various tools that have been developed, and the type of data that are on the data hub (e.g., microscopy, pol curves, XRD, XPS). Each data file represents one of these data. We hope these two slides better communicate the level of participation and the complexity of the data in the Data Hub.
• Although individual projects have milestones and go/no-go points, the AWSM Consortium lacks clear success metrics at a higher level to guide its pathways and projects.
Response: The success metrics for the consortium are varied. The overall metric is cost reduction (through performance and durability gains) for the various water-splitting materials, remaining cognizant that they are at very different levels of technological maturity. Interactions and enabling the FOA projects is key to this and thus serves as metrics for the consortium. In addition, the existence of supernodes (with their more traditional research metrics, shown on FY19 Supernode Annual Milestones [AM] slide in “Reviewers Only slides”), the data analysis and data hub, and the research progress of individual nodes all provide further metrics for measuring success.
HydroGEN: Advanced Water Splitting Materials 27
Proposed Future Work
• Core labs will execute HydroGEN nodes to enable successful phase 2 project activities and work with new phase 1 projects
– Core labs’ interaction with a specific project will end if that project does not achieve its go/no-go decision metric
• Collaborate and perform integrated research in the 5 supernodes• Integrate whole system (capability nodes, FOA awardees, data infrastructure,
TT/A) to accelerate the R&D of HydroGEN critical materials development to deployment
• Continue to review, maintain, and develop current and identify new relevant HydroGEN capability nodes
• Continue to develop a user-friendly, secure, and dynamic HydroGEN data hub that accelerates learning and information exchange within the HydroGEN EMN labs, their partners, and other EMN, AE, PEC, and STCH communities
• Work closely with the Benchmarking Team to establish benchmarking, standard protocols, and metrics for the different water-splitting technologies
• Outreach
Any proposed future work is subject to change based on funding levels

The goal is to synthesize and demonstrate high performing, durable, and economically-affordable AEMs in water-fed AEM electrolysis.
Low Temperature Electrolysis (LTE)LANL demonstrated 4x higher in water-fed AEMelectrolyzer performance (0.243 A/cm2 at 1.8 V), compared to FY2018, using LANL developed carbon-free and PGM-free perovskite OER catalyst and SNL AEM membrane. The goal is to achieve low cost H2production via high performing, durable, and low cost PGM-free catalyst AEM electrolysis. NREL XPS and in-situ testing nodes helped LANL understand the OER catalyst surface composition and MEA electrode performance.

Solar Thermochemical (STCH) Water SplittingThe University of Colorado Boulder, with NREL’s DFT node, developed and applied machine learning (ML) to accelerate STCH materials discovery, identifying several hundred stable STCH perovskites from over 1.1 million possible candidates, with 92% accuracy. SNL’s stagnation flow reactor and High-Temperature XRD nodes were used to experimentally validate water splitting kinetics and crystal structures for a select number of materials, providing critical feedback to develop rapid kinetic screening techniques of materials. Four materials have also been demonstrated to have H2productions >200 μmol/g/cycle at Tred =1450°C and ΔT=250°C, and results compared to computational predictions.
